struts2で表示タグの編集、削除リンクを作成したい。これは私のjspコードです
<%@ page contentType="text/html; charset=UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<%@taglib uri="http://displaytag.sf.net" prefix="display" %>
<html>
<head>
<title>Contact Manager - display tag Example</title>
<link href="css/style.css" rel="stylesheet" type="text/css" />
</head>
<body>
<display:table name="contactList" requestURI="" pagesize="10" export="true" cellpadding="1" uid="sr" cellspacing="1" size="50"
defaultorder="ascending" sort="list" style="width:850"
id="row">
<display:column property="id" title="serial no" sortable="true" />
<display:column property="lastName" title="TV Show" sortable="true" />
<display:column property="firstName" title="User Name" sortable="true" />
<display:column property="emailId" title="Email Id" sortable="true" />
<display:column media="html"
title="Delete"
style="text-align:center">
<s:url id="deleteUrl" action="deleteLink">
<s:param name="id1" value="#attr.row.id" />
</s:url>
<s:a href="%{deleteUrl}">
Delete
</s:a>
</display:column>
<display:column media="html"
title="edit"
style="text-align:center">
<a href="deleteLink?id=<s:property value="id"/>">edit</a>
</display:column>
<display:setProperty name="export.excel.filename" value="ActorDetails.xls"/>
<display:setProperty name="export.pdf.filename" value="ActorDetails.pdf"/>
<display:setProperty name="export.pdf" value="true" />
</display:table>
</body>
</html>
これは私のアクションクラスです：
package net.viralpatel.contact.view;
import java.util.List;
import net.viralpatel.contact.controller.ContactManager;
import net.viralpatel.contact.model.Contact;
import com.opensymphony.xwork2.ActionSupport;
public class ContactAction extends ActionSupport implements ModelDriven<Contact>,Preparable {
private static final long serialVersionUID = 9149826260758390091L;
private Contact contact;
private List<Contact> contactList;
private ContactManager linkController;
public ContactAction() {
linkController = new ContactManager();
}
public String getRecords()
{
contactList =linkController.lSist();
return SUCCESS;
}
public String deleteRecord()
{
System.out.println(contact.getId());
return SUCCESS;
}
public Contact getContact() {
return contact;
}
public List<Contact> getContactList() {
return contactList;
}
public void setContact(Contact contact) {
this.contact = contact;
}
public void setContactList(List<Contact> contactsList) {
this.contactList = contactsList;
}
@Override
public Contact getModel() {
return contact;
}
@Override
public void prepare() throws Exception {
// TODO Auto-generated method stub
contact = new Contact();
}
}
jspページからContactActionクラスのdeleteRecord（）メソッドに削除する行の属性の値を取得するにはどうすればよいですか？ここに声明
System.out.println("ID IS "+contact.getId());
出力を返します：ID IS null
いくつかの解決策を提案してください。
ありがとう
これはContactBeanです
